# API keys

> Create and manage inference and account keys

MuleRouter provides two key types:

| Key type          | Use                                                                    |
| ----------------- | ---------------------------------------------------------------------- |
| **Inference key** | Model requests such as LLM, image, video, speech, and music generation |
| **Account key**   | Account APIs such as balance queries                                   |

The two key types are not interchangeable. Account keys currently support [Balance](/docs/api-reference/endpoint/user/billing/balance) access only.

## Create a key

1. Open [API Keys](https://www.mulerouter.ai/app/api-keys) in the Console.
2. Choose **Inference keys** or **Account keys**, then click **Create key**.
3. Copy the key immediately. The full value is shown only once.

## Manage keys

The Console lists each key and its metadata. You can enable or disable inference keys and permanently revoke either key type.

<Warning>
  Store keys in a server-side environment variable or secret manager. Never
  expose them in browser or mobile application code.
